A BRUGG GROUP COMPANY
Flexible, Insulated, Monitorable & Self-Compensating
CASAFLEX is a pre-insulated flexible pipe system for steam condensate lines and district energy applications. Supplied in continuous lengths, it is engineered to handle high temperatures and pressures while offering excellent thermal insulation, self-compensation, and integrated monitoring capabilities.
The spiral-corrugated stainless steel core of CASAFLEX provides exceptional stability, allowing for direct routing through foundations all the way to the transfer station. This makes it ideal for demanding environments — from compact urban corridors to sensitive natural landscapes.
The spiral corrugation also enhances ventilation and delivers superior resistance to internal buildup, ensuring efficient, long-term operation for both district energy networks and steam condensate systems.
CASAFLEX stands out with its integrated monitoring capability through dedicated monitoring wires, offering operators greater control and reliability. Combined with its capacity to handle high pressure and temperature loads, it delivers a robust solution for modern steam condensate lines and district energy systems.
Additionally, CASAFLEX can be easily integrated into existing plastic-jacket pipe networks, making it a highly adaptable choice for both new projects and retrofits.

District energy systems use industrial waste heat or energy from central heating plants to deliver thermal energy to buildings through insulated pipelines. This approach enables efficient, centralised energy distribution while saving resources.
CASAFLEX – a flexible, stainless steel pipe system – offers an ideal solution for expanding or upgrading district energy networks and steam condensate systems. With its easy installation, high resistance to temperature and pressure, and built‑in monitoring capability, CASAFLEX delivers reliable performance for demanding applications.
High operating temperatures cause pipeline materials to expand, placing significant demands on system design. CASAFLEX solves this challenge with its self-compensating design: the spirally corrugated stainless steel carrier pipe naturally absorbs linear expansion.
This built-in flexibility removes the need for external expansion joints or extra bends in most installations. The result is a more compact system, faster installation times, and enhanced operational safety — making CASAFLEX ideal for both local and district energy networks as well as steam condensate line applications.
CASAFLEX is engineered for demanding environments and complex routing. Its highly flexible, spirally corrugated stainless steel inner pipe allows installation in very tight radii, even in uneven terrain or confined spaces — without the need for additional fittings or expansion joints.
Integrated monitoring wires enable reliable leak detection along the entire pipe length, enhancing operational safety and supporting proactive maintenance planning. This makes CASAFLEX an excellent choice for both local and district energy networks as well as steam condensate line and condensate line applications.
CASAFLEX serves as an ideal solution for short to medium-distance connections within local energy networks. Its exceptional flexibility makes it particularly well suited for local heating and steam condensate line applications. The system’s design allows for easy integration of multiple connection points, even in tight or confined spaces, while maintaining consistent sealing and operational reliability.
With a small bending radius, CASAFLEX enables fast, material-efficient installation in densely built environments. Reduced trench widths further shorten construction time and minimize disruption to existing infrastructure. This makes CASAFLEX a top choice for both new installations and upgrades within local and district energy systems.
The CASAFLEX district energy pipe stands out as a high-performance solution for large-scale underground energy distribution. Engineered for extended supply networks, CASAFLEX delivers exceptional reliability over long distances with continuous operation at up to 150 °C and 25 bar.
Its robust spirally corrugated stainless steel inner pipe, combined with advanced thermal insulation, ensures minimal heat loss and high efficiency — making CASAFLEX the optimal choice for modern district energy and condensate line applications.
As a house connection pipe, CASAFLEX offers a reliable solution for the direct connection of buildings to local or district heating networks. At the transition from the main pipe to the building, the system impresses with its easy-to-install design.
As it is supplied on rings from the factory, the pipe can be laid directly to the transfer station - even through foundation ducts. The small number of connection points increases operational reliability and significantly reduces installation costs.
CASAFLEX has a modular design and offers high connection compatibility thanks to its extensive range of accessories — e.g. weld-free connection joints, wall ducts, wall sealing rings, etc. All system components are matched to every dimension.
CASAFLEX is supplied in continuous lengths on drums, minimising connections and significantly reducing installation times. Delivered pre-assembled for specific projects, it allows for efficient on-site adjustments. Thanks to its low weight and high flexibility, even larger dimensions can be easily transported and installed — making it ideal for urban construction sites and challenging terrain.
Supplied on drums, CASAFLEX can be unrolled and installed on site in the required length. Its pressure-tight, factory-tested connection technology ensures safe and time-efficient assembly.
CASAFLEX is not only ideal for new projects but also perfectly suited for integration into existing local or district energy networks. The system is fully compatible with common plastic casing pipe systems and can be flexibly adapted using a wide range of connection and transition solutions. Whether as a replacement pipe in network renovation or as an extension of existing infrastructure — CASAFLEX ensures a seamless connection with minimal effort.
The compact routing enabled by small bending radii and the elimination of additional compensation components reduces the depth of intervention and lowers material usage in civil engineering. This conserves resources and positively impacts the environmental footprint of the entire project.
